Most healthcare IT problems are really integration problems
A lab result that never reaches the EHR, a payer feed that silently drops claims, an interface engine nobody dares upgrade: these are the failures that hurt clinicians and patients. They rarely come from one bad system. They come from the joins between systems. That is why our healthcare practice starts with HL7, FHIR and EDI integration and works outward to the cloud, security and software around it.
We build and support Mirth Connect and Open Integration Engine channels, FHIR R4 and SMART on FHIR APIs, HIE connections and OpenEMR customisation. We also operate our own clinic, pathology-lab and veterinary products, so we know what a busy front desk or a lab bench needs from software, not just what the standard says.
Problems healthcare teams bring to us
If any of these sound like your week, we have probably solved a version of it before.
“Our interface engine is a black box”
Channels written years ago by someone who has left, no documentation, and an upgrade everyone keeps postponing.
“Results go missing and we find out from clinicians”
Errors queue up silently. No alerting, no dashboards and no idea how many messages failed overnight.
“We need FHIR, but our systems speak HL7 v2”
A partner, regulator or app vendor wants FHIR APIs while the core systems still emit pipe-delimited messages.
“The security questionnaire is longer than our codebase”
Hospitals and payers ask for HIPAA evidence, pen-test reports and policies before they will sign.
“Every new lab analyser is a three-month project”
Each instrument and LIS has its own dialect of HL7 or ASTM, so every connection starts from scratch.
“Our front desk spends the day on the phone”
Missed calls, no-shows and manual reminders cost appointments and staff time every single day.
Healthcare solutions, from interfaces to the front desk
Pick the problem closest to yours. Each one links to the services and products that deliver it.
Interface engine rescue & support
The challenge
A Mirth Connect (or similar) estate grown over years, with undocumented channels, an unsupported version and failures nobody notices until a clinician calls.
Our approach
We inventory every channel, document message flows, add error queues and alerting, then plan a safe upgrade or move to the Open Integration Engine. After that we can run it for you with a monitored support SLA.
What you get
- Channel inventory and flow diagrams
- Alerting on failed and stuck messages
- Tested upgrade or migration plan
- Optional 24/7 monitored support
FHIR APIs on top of legacy systems
The challenge
Partners, apps and US payer rules need FHIR R4 APIs, but your source systems speak HL7 v2, CCDA or a proprietary database.
Our approach
We put a FHIR facade or server in front of what you have, mapping HL7 v2 and CCDA into US Core profiles, securing it with SMART on FHIR (OAuth 2.0) and testing conformance before go-live.
What you get
- FHIR R4 server or facade
- HL7 v2 / CCDA → FHIR mappings
- SMART on FHIR authorisation
- US Core conformance testing
HIPAA-aligned cloud & evidence
The challenge
You are moving clinical workloads to AWS, Azure or GCP and need to show auditors and customers that PHI is protected.
Our approach
We design landing zones with encryption, least-privilege access, centralised audit logging and backups, run a penetration test, and keep evidence current so a security questionnaire becomes an export, not a fire drill.
What you get
- HIPAA-aligned landing zone (IaC)
- Audit logging and access reviews
- Penetration test with retest
- Policies and evidence in a GRC tool
Lab & analyser integration
The challenge
Each analyser, middleware and LIS uses a slightly different HL7 or ASTM dialect, and reports still get typed, printed or emailed by hand.
Our approach
We build reusable analyser drivers and order/result channels, add barcode-based sample tracking and push signed reports to doctors and patients digitally. Our own PathLab Software is built on the same patterns.
What you get
- HL7 / ASTM analyser interfaces
- Order and result routing to HIS/EHR
- Report delivery on WhatsApp or portal
- Error dashboards for the lab team
AI front desk for clinics
The challenge
Calls go unanswered after hours, patients forget appointments, and staff juggle phones, WhatsApp and the waiting room at once.
Our approach
We deploy AI call answering, WhatsApp/SMS reminders and a shared inbox, either through our own products or as a custom build connected to your practice-management system.
What you get
- 24/7 AI call answering and booking
- Automated WhatsApp and SMS reminders
- One inbox for every patient message
- Integration with your PMS or EHR
Rules and standards your systems have to meet
Healthcare compliance is about evidence as much as controls. Here is what we design for, and where each rule currently stands.
HIPAA Security Rule
Applies to covered entities and their business associates. HHS proposed a major update in January 2025 (mandatory MFA, encryption and asset inventories). It is not final yet, but it is a sensible baseline to build to now. See our HIPAA on AWS guide.
CMS Interoperability & Prior Authorization rule
CMS-0057-F requires impacted payers to run FHIR-based Patient Access, Provider Access, Payer-to-Payer and Prior Authorization APIs, mostly from 1 January 2027. We build and test those APIs.
ONC certification & information blocking
HTI-1 moved certified health IT to USCDI v3 from 1 January 2026, and information-blocking rules penalise unreasonable barriers to data access. US Core-conformant FHIR APIs are how you show you comply.
TEFCA & HIE connectivity
TEFCA has been live since December 2023 through designated QHINs, alongside regional HIEs using IHE profiles (XDS, PIX/PDQ). We connect systems to both.
ABDM & the DPDP Act
The Ayushman Bharat Digital Mission uses FHIR R4-based profiles for health-record exchange, and the Digital Personal Data Protection Act, 2023 governs consent and security for patient data.
GDPR for health data
Health data is “special category” data under GDPR, which calls for a lawful basis, data-protection impact assessments and strict access control. We build those controls into the architecture.
Status as of October 2026. Regulations change; we help you design, implement and evidence technical controls. Legal interpretation belongs with your counsel, and certifications or audit opinions are issued by independent bodies, not by us.

Questions healthcare teams ask us
Where our work involves access to protected health information, we can enter into a BAA as part of the contract. We also design cloud environments so that your cloud provider’s BAA covers the services in use.
Yes. We start with an inventory and documentation pass, add monitoring and alerting, then support the channels under an agreed SLA. This covers both commercial Mirth Connect (NextGen, version 4.6 onwards) and the open-source Open Integration Engine fork.
Usually by adding a FHIR server or facade that maps your HL7 v2 and CCDA data into FHIR R4 resources conforming to US Core, secured with SMART on FHIR. Your source systems do not need to change on day one.
We integrate with major EHRs through their supported interfaces: HL7 v2 feeds, FHIR APIs and vendor app programmes. Some vendor programmes require your organisation to sponsor or register the integration, and we work through that with you. We are not a certified partner of any EHR vendor.
A standard HL7 v2 feed between two systems that are already reachable often takes days to a couple of weeks, including testing. Analyser interfaces, FHIR facades and HIE onboarding take longer, mostly because of partner testing windows. We give you an estimate after the discovery call.
Clinic Answering Service is built for US practices and HIPAA requirements. Our India-focused products (dental, physio, pathology and veterinary) are built for Indian clinics and data-protection law. Ask us for the security documentation of any product you are evaluating.
